To all whom 1f/may concern: y

Be it known that Josigrrr RosoHAor-I, a citizen of the RepublicofvSwitzerland, and

a resident of Campgaw, in the county of.

improved frame for embroidering"handker-v chiefs, gloves, stockings,scarfs, etc., which is efficient in operation.

Several embodiments of the invention are shown in the accompanyingdrawings, and will be more fully described hereinafter and finallypointed out in the claims. p

In the accompanying drawing, Figure 1 is a plan view of one embodimentof the invention, Fig. 2 is a longitudinal section on line 2 2 of Fig.ll, Fig. 3 is a transverse section on line 3-3 of Fig. V1-,`Fig. 4 is aplan view of the device, opened, Fig. 4a is a transverse section on line4& 4a of Fig. 4, Fig. 5 is a longitudinal section on line 5-5 of Fig. 4,Fig. 6 is a plan view Vof another embodiment of the invention, Fig. 7 isa transverse section on line 7 7 of Fig. 6, Fig. 8 is a plan view ofanother embodiment, Fig. 9 shows still another embodiment, Fig. 10 `is asection on line 10-10 of Fig. 8, Fig. 11 is a section on line 11--11 ofFig. 9, Fig. 12 is a plan, showing a plurality of embroidery frames,embodying the invention, arranged in series, Fig. 13 is a transversesection on line 13-13, Fig. 12, and Fig. 14 is a longi v tudinal sectionon line 14-14, Fig. 12.

Similar character ofv reference lindicate corresponding parts throughoutthe various figures of the drawing.

Referring to the drawings, and more par-V ticularly to Figs. 1 to 3, theframe there .shown comprises rails 12 between which eX- tendconnecting-members 13, said members 13l are provided with clamping rods14 hinged at 15, which have manipulating ends 16, whereby they can beplaced between sidemembers 17 which are secured to the members 13, andthereby clamp the material 21 between the rods 14 and the members 17.Between the members 17 at either side of the frame, a stretcher-frame isarranged which consists of movable side bars 20 adapted to engage thefixed members 17 and press between the bars 20 and the members 17 thematerial 21 to be embroidered.v It will be i l noted that the expandingbars 2O 4press the material into the members 17, and that also the rods14 press the material intov the lmembers 17. The movableside bars areprovided with face strips 48 of rubber, which enter into the U-shapedstationary members 17. Thereby a very secure hold of the material isobtained, and by the rods 14 the outstanding flaps indicated by 22 are.prevented from freely moving, and thereby coming into contact with anyof the moving parts ofthe machine. The side bars 20 are moved intoexpanding position by means of inclined co operating surfaces, and forthis purpose each `of the side bars 2O is provided at 'each end with yabearing member 25 which has at one side thereof, at 26, a beveled face.Thiswbeveled face is engagedv by a cam 28, which has a bevel 27 at each'end thereof. Cam `28 is secured to the shaft 29, and the latter has ateach end thereof a head 30. Between the heads 30 and the members 25,springs 31 are arranged. The rail 12 carries an extension 33 which isadapted to beengaged by .a clamping member 34 loosely mounted -at itsends in the bars 20, for clamping the material between the parts 33 and34. The con-struction of the expanding devices at the opposite end ofthe frame is similar to that already described, except that the cam 28is loose on its shaft 45 and the latter is secured at its ends in the-mem bers 17.

When the handle is raised by the operjator, the cam 28 is thereby movedaround its'aXis, and thereby the springs 31 force the members 25inwardly and carry with them the side bars 20, the coperating beveledportions 26 and 27 permitting inward movement. Thereby the bars 20become disengaged from the fixed members 17 and ,the frame may beopened, the bars 20 swinging on shaft as an axis, into the positionshown in dotted lines in F ig. 5, land permitting removal ofthematerial, the rods 14 having been previously opened away from themembers 17. By the device described, a very efficient frame is produced,las by the coperation of the parts the material is firmly held inposition for the embroidering to take place by the usual and well-knownma-Y chines.

In the embodiment shown in Fig. 6, the operating handle is arranged atthe side of the frame, and has a beveled hub 51 cooperating with abeveled portion 52to which beveled portion 52 the movable sidebar 53 issecured. The'side-bar 54 is like the bar 53 and operated by a cam 18 onthe shaft 55. Intermediate the beveled members 52 and abutments 56 0nthe shaft are spreading-springs 57. Between the two abutments 56, theshaft is arranged to form a crank-arm, as indicated by 58, and thiscrank-arm is engaged by a sleeve 59 on a clamping member 60. Member 60has lateral lugs 61 which are guided inv the bars 53 and 5%. Theconstruction of the expanding devices at the opposite end of theapparatus is similar to that already described, except that the shaft 36is mounted at its ends in bearings 37 supported on the frame 63, wherebythe outer frame 53, 54 may be swung away from the inner frame 63 foropening the apparatus. By the arrangement described, all the side-barsmay be brought into and out of clamping position very rapidly by theaction of the handles 50. The side-bars 53 and 54 engage thev U-shapedfixed side membersi62 of the frame 63, and the clamping members 60engage the end portions 19 thereof, and thereby clamp in position thematerial to be embroidered. The frame 63 is secured at its ends to rails35 for attachment to the embroidery machine.

In the embodiment shown in Fig. 8, the side bars and 7l have sleeves 72and 73, between which and heads 74 and 75 on the shaft 38, springs 76are arranged. An expanding device, consisting of two cam-levers 77 and78 is provided, whereby the bars 70 and 71 are moved into outermostposition against the action of the springs 76.

In Fig. 9 another embodiment is shown, in which the movable side bars 80and 81 have sleeves 82 and 83 pressed away from the fixed members 84 and85 by springs 86. rFhe sleeves 82 and 83 are secured to pins 88 whichare guided in the members 84, 85, and said pins have their inner ends 89engaged by a cam-plate 90 which is rotatable on a center stud 91. Theplate 90 has manipulating knobs 93, whereby the plate may be rotated.When it is arranged with its longest axis in line with the guiding pins88, it serves to press the pins and thereby the side-bars 8O and 81outwardly against the action of the springs 86, and thereby clamp thebars 80 and 81 against the inclosing side members 84 and 85. When,however, this plate is rotated to take the position shown in dottedlines in Fig. 9, then the springs 86 cause -the bars 8O and 81 to moveout of the inclosing side members and permit the material to be removedfrom the frame.

The frames described or others embodying the same principlesmay be usedsingly,

but in practice a number of the same are mounted consecutively on thesame rails. Such a construction is shown in Figs. 12 to 14 inclusive.Referring to these figures, the rails 1101.111 are of such shape as toreadily fit into the embroidery lnachine. Between the rails are arrangedtransvcrselya plurality of fixed or stationary frame members, as, forinstance, 112, 113, 114, 115. Said stationary frame members areequidistantly spaced apart. Between each two adjacent fixed framemembers is arranged al swinging stretcher frame. Said frame comprisestwo side-bars 116, 117, one of which is adapted to engage one edge ofthe fixed member at one side and the other of which is adapted to engagethe edge of the member at the other side of the stretcherframe when thetwo bars are expanded from each other for clamping the article to be emfbroidered. At one end each of said side-bars 116, 117 is pivoted to therail, as, forfexam.- ple, the rail.111, as shown in Figs. 12 and 13.This is accomplished by providing ,a longitudinal rod 118, which may beSecured in lugs 119 atrthe ends ofthe fixed frame members. Each side-baris provided at its pivoted end with a bearing member mounted on the rod118. The bearing member 120 of the side-bar 116 has its inner facebeveled in one direction, and the bearing member 121 of the side-bar 117has its inner face beveled in the opposite direction. Between saidbearing 4members is an operating Vcam 122 rotatably mounted on the rod118, and provided with a handle 123. Springs 124 on the rod 118 betweensaid lugs 119 and the bearing members, press the latter constantlyinwardly against the cam 122. At the oppo- H site ends the sidebars 116,117 are connected by a pin 125 which passes-through bearing members 126,127 and a cam member 128,` said bearing members and cam correspond? ingin their general form to those at the op-. posite end of thestretcher-frame, and the cam 128 is provided with a corresponding lll)handle 129. Springs 130 between heads 131 on the outer ends of the pin125 and the bearing members 126, 127 constantly press the bearingmembers inwardly upon the cam 128. The action of the springs at bothends of the frames tends to move the bars 116 and 117 toward each otherthroughout their lengths, whereby the stretcher-frame is contracted inwidth, so that the article to be. embroidered may be insertedbetweensaid side-bars and the adjacent fixed frame mem-- bers. Forsecurely holding the article, the fixed members are provided at theiredges with concave seats 132 in which are adapted to enter convex rubberfacing-strips 133, which are secured to the side-bars. The article to beembroidered having been inserted in the frame when the same is inlopen,ycondition, as shown at the righthand side raarste of Fig. 1'2,the'eain-operatn'g handles 123 and 129 are 4now swung inwardly "intoytheposition shown at the, left-hand .side of Fig. 12. By such operation'thecams 122 and 12S are caused to spread apart the bearing mem-` bers oftheside-bars, and thereby the sidebars themselves,`i'nto clampingengagement with the stationary framefmembers 112 and 113, and therebythe article is drawn taut in the frame, the positionofthe same beingindicated in dotted lines 140 in Fig. 12. For securing anyloosemateria'l which might extend beyond 'the limits necessary to beclamped for embroidering spring-clips 142 are provided, under which thesurplus material may be gathered, as shown in Fig. 14, and thereby lheldduring the embroidering operation.

The fixed frame-members may have any suitable form. In Figs. 12 and 13,the member 112 is a simple transverse bar secured at its ends to therails 110 and 111. The fixed frame-members are widened at their ends, asshown at 144, and have a contracted middle portion 143 between'the'same.

One edge of the ixed member thus recedesy at its middle from the edge ofthe adjacent member, and forms with the same an approximately triangularspace in which the portion of the fabric to be embroidered is located.This construction economizes space and lends strength to the entireapparatus, and has the advantage, when embroidering cornered articles,such as handkerchiefs, that the same may be placed with thecorner-portion thereof in said triangular space, as shown in dottedlines in Fig. 12, thus giving a tight clamping action and stretching ofthe fabric at said portion.

Vhen the embroidering is completed, the operating handles 123 and 129are moved by the operator outwardly into the position indicated at theright-hand side of Fig. l2, the side-bar-springs retract the side-barsof the stretcher-frame, and the material is thereby freed, so that thesame may be removed. For preventing the cams 122 and 128 from beingforced in return direction after they have once been swung into innerposition, the widest portion of the cam is so located as to be slightlybeyond the centers, that is, beyond the widest portions, of the bearingmembers, when the cam is in innerposition. The operating handles 123 and129 are limited in their inward movement by abutment with the rails 110and 111, as shown in Fig. 13.

The frame is made of any desired metal or metals. Y For securinglightness in weight parts of the frame, as for example, the fixedframe-members, may be made of aluminum.

Three frames have been shown in Fig. 12, but any desired number may beused, mounted together in the manner shown, for use in a single machine,and a number of such sectinnsrxforexampleyeight br as "many astwentyesix, maybe used, according. toV the capacity of themachinevemployed. s; Several embodiments of the invention have beendescribed.
